Wireless sensor network based on P2P technology

The utility model discloses a wireless sensor network based on P2P technology. The wireless sensor network comprises a sensor network layer, a gateway layer and a processing layer which are in a P2P protocol structure, wherein the sensor network is formed by interconnection of wireless sensors and achieves self information release, sensor data collecting, and simple data processing; the network layer is composed of gateway nodes, each gateway node is connected with the wireless sensor network and is integrated in a P2P network; and the processing layer is composed of gateway layer terminals with strong task processing ability, namely super terminals, the processing layer decomposes the task requirement into sub-tasks, sends the sub-tasks to the gateway nodes to be distributed, receives and processes feedback data for presentation. By employing the multi-layer network structure mode, effective sensing data reuse is achieved, information amount going in or going out of the sensor network and communication cost
